The grinding time increased significantly (p < 0.05) with the increasing moisture content from 8 to 20% (db) under both the cryogenic and ambient grinding conditions as shown in Fig. 3. The grinding time showed a linear increasing trend as shown in regression equations in Table 1. Moisture content of a feed influences its grinding time.
